Title: A transimpedance amplifier for detecting very small chromatograph or mass spectrometer currents with a greater bandwidth
Inventor: HAMILTON THOMAS DANIEL SCOTT
IPC: H03F3/08
Filed: 2002-08-03
Abstract: A transimpedance amplifier for detecting very small dynamic currents (less than a picoampere) comprises an operational amplifier 204 with negative feedback through a parallel RC network C2,R2. The feedback network is coupled to a lag-lead tap 218 on a series output RC network R1,R3,C1 with a similar time constant. The provision of the small resistor R3 increases the operable bandwidth of the amplifier allowing relatively small currents to be measured with greater accuracy. The transient response exhibits reduced ringing. The introduction of a second operational amplifier (307,figure 4) in the forward path of the loop increases open loop gain, thereby improving gain accuracy. Bandwidth and response time can be further improved by providing the second amplifier with a differentiating (lead) response (C4,figure 5). The improved amplifier may be used in a chromatograph or a mass spectrometer.

Title: Fluid level detection sensor
Inventor: SHI ZHONG-YOU
IPC: H04B10/2581
Filed: 2002-10-16
Abstract: A non-mechanical fluid level sensor is based upon Light Communication Channel (LCC) technology.

Title: Determination of formation anisotropy using multi-frequency processing of induction measurements with transverse induction coils
Inventor: TABAROVSKY LEONTY A
IPC: G06F19/00
Filed: 2002-04-02
Abstract: Skin-effect corrections are applied to measurements made by a transverse induction logging tool to give corrected measurements indicative of vertical conductivities of a formation. Data from a conventional induction logging tool (10) are inverted or focused to give an isotropic model of formation resistivity (301). A forward modeling is used to derive from the isotropic model measurements that would be expected with a transverse induction logging tool (303). Skin-effect corrections are applied to these expected measurements (305). The formation anisotropy is determined from the skin-effect corrected transverse induction logging measurements, the skin-effect corrected expected measurements and from the isotropic model conductivities (311).

Title: Permanent magnet Synchronous motor and Commutator
Inventor: CHEN XIAOJIANG
IPC: H02P25/02
Filed: 2004-05-05
Abstract: A low-cost sine-wave drive for a 3-phase permanent magnet synchronous AC motor 20 (PMSM) in open-loop control is based on the measurements of two linear Hall sensors 16 positioned at a given electrical angle acting as an electronic commutator. The two hall sensors are excited by the sinusoidal flux distributions of magnetic ring with the same pole number as the PMSM rotor magnet, and the outputs of the Hall devices are normalised by a two-phase-type phase-locked-loop 222 in order to reduce the impact of the sensor mounting non-uniformity during mass production. Signals representing normalised orthogonal components of each sensor are ten used to control sinusoidal energising currents supplied to the motor. The peak torque and speed of the motor is simply controlled by adjusting the amplitude of pulse width modulation (PWM) carrier 26, and smooth torque control is achieved due to sinusoidal 3-phase currents.
